Description
Technical field
The utility model is related to structures under wind testing equipment field, and in particular to one kind is used for the test of wind load test wind profile
Pitot tube fixing device.
Background technology
In structures under wind research process, it is often necessary to which stream field wind speed is measured, usual method of testing is to utilize one
Pitot tube tests the wind speed of some measuring points of same position different height, finally obtains the mean velocity profile in flow field, this test
Method is unable to synchronism detection on the testing time, and point position easily produces error, horizontal direction can not mobile test, be
More facilitate accurate test, it is necessary to propose a kind of using multiple Pitot tube vertical array different heights and horizontal direction can profit
The flow field wind speed measuring device moved with track.
Utility model patent《A kind of bent device of Flow Field in Wind Tunnel test》（The patent No.：201320010451.4）Disclose
A kind of bent structure of Flow Field in Wind Tunnel test, but there is problems with above-mentioned technical proposal：1st, two pieces of circular steel plates are fixed on
Top plate and base arrangement volume are excessive, not easy to operate.2nd, Pitot tube distance is changed by the stirrup being fixed in round steel pipe, it is real
There is certain error in border adjustable range, cause flow-field test precision not accurate enough with desired value.3rd, device needs adjustment after fixing
Horizontal direction position, then the device can not adjust constantly.
Utility model content
In order to solve the above problems, many root skin trustships can quickly be fixed what can simultaneously be positioned by the utility model there is provided a kind of
Device.
The technical solution adopted in the utility model is：It is a kind of to fix dress for the Pitot tube that wind load test wind profile is tested
Put, including horizontal rail, support, clamping plate, Pitot tube and pressure acquisition instrument；The section of described support is in inverted T-shaped, in support
Side is provided with clamping plate, and described support is bolted with clamping plate；Provided with some Pitot tubes between clamping plate and support；Institute
One end connection pressure acquisition instrument for the Pitot tube stated；Described frame bottom is provided with wheel, and described wheel can be in horizontal rail
Rolled in road.
Further, horizontal deep-slotted chip breaker, adjacent two are equipped with the part of fixed Pitot tube on described support and clamping plate
The distance of individual deep-slotted chip breaker is identical.
Further, ten bolts hole and one-to-one corresponding are equipped with described support and clamping plate；Described bolt hole totally five
Row, often arranges two, and be evenly distributed on the lower section of deep-slotted chip breaker.
Further, described Pitot tube is L-type standard pitot tube, sets five root skin trustships altogether from top to bottom, per root skin support
Pipe is arranged in the deep-slotted chip breaker between support and clamping plate.
The beneficial effect that the utility model is produced：The utility model device is simple, operation is convenient, with low cost, facilitates group
Dress and dismounting, measuring point wind velocity condition at five groups of different heights can be measured simultaneously, while going back shiftable track measurement direction along ng a path
Diverse location wind velocity condition, can conveniently be applied to flow measurement wind velocity condition.
Brief description of the drawings
Fig. 1 is positive structure schematic of the present utility model；
Fig. 2 is left view of the present utility model；
Fig. 3 is top view of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As Figure 1-3, the utility model is a kind of Pitot tube fixing device tested for wind load test wind profile, should

Font is arranged on the top of horizontal rail 5, is provided with the bottom of support 1 in four wheels 4, the insertion horizontal rail 5 of wheel 4.Branch
Frame 1 is moved to behind a certain position fixes wheel in horizontal rail 5, prevents wheel 4 from departing from horizontal rail 5 together with support 1.
It is provided with the side of support 1 on clamping plate 2, support 1 and clamping plate 2 and is equipped with five row's bolts hole 6, is often arranged bolt hole 6 and exist
Two holes are set in same horizontal line and spacing is consistent.Pitot tube 7 is provided between support 1 and clamping plate 2, Pitot tube is L-type mark
Quasi- Pitot tube, sets five altogether from top to bottom, is arranged at per root skin trustship in the deep-slotted chip breaker between support and clamping plate.
Pitot tube 7 is embedded in after the deep-slotted chip breaker between support 1 and clamping plate 2, and bolt is inserted into fixed in bolt hole 6.Pitot tube 7
Other end connection pressure acquisition instrument 8, the synchronous acquisition of five root skin trustship 7 can obtain vertical direction diverse location measuring point wind speed
Situation, support 1 is moved into another position along horizontal rail 5 can measure wind velocity condition at other positions.
Described above is only preferred embodiment of the present utility model, is visualized for those skilled in the art from above-mentioned
Hair, without performing creative labour, made a variety of conversion are all fallen within protection domain of the present utility model.
